服务器端：



import java.net.*;

import java.io.*; 

import java.util.*;

public class Server{

	private ServerSocket ss;

	private Map<String,Socket> map = new HashMap<String,Socket>();

	private BufferedReader in;

	private PrintWriter out;



	public Server() {

		try {

			ss = new ServerSocket(6000);

			//开启一个发送线程

			SSendThread sst = new SSendThread(this);

			new Thread(sst).start();

			while(true) {

				Socket socket = ss.accept();

				ServerProxy sp = new ServerProxy();

				sp.acceptClient(this,socket);

			}

		}catch (IOException e) {

			out.println("wrong");

		}

	}



	public boolean isQuit(){

		return false;

	}

	public void quit(boolean b){



	}



	public void addClient(String name,Socket socket){

		if(getSocket(name) == null){

			map.put(name,socket);

		}

	}



	public Socket getSocket(String name){

		return (Socket)map.get(name);

	}

	public static void main(String[] args) {

		new Server();

	}

}



/**

* 服务器代理，用于处理一个客户端的请求。一个客户端对应一个代理

*/

class ServerProxy{

	private SSReceiveThread rt;

	public void acceptClient(Server server,Socket socket)

	{

		rt = new SSReceiveThread(server,socket);

	}

}

class SSReceiveThread implements Runnable{

	private Socket socket;

	private Server server;

	public SSReceiveThread(Server server,Socket socket){

		this.server = server;

		this.socket = socket;

	}

	public void run(){

	    String RemoteIP = socket.getInetAddress().getHostAddress();

		String RemotePort = ":"+socket.getLocalPort();

		BufferedReader in;

		while(true){

			if(server.isQuit()){return;}

			try {

			in = new BufferedReader(new InputStreamReader(socket.getInputStream()));

			char[]  buffer = new char[1024*1024*5];

			String lineStr = "";

			/*while((lineStr = in.readLine()) != null){	

				System.out.println(lineStr);

			}*/

			int len = in.read(buffer,0,buffer.length);

			String context = new String(buffer,0,len);

			String name = parseContext(context);

			server.addClient(name,socket);

			System.out.print(context);

			}catch(IOException e) {

				System.out.println("SSReceiveThread Wrong");

				e.printStackTrace();

				return;

			}

		}

		

	}

	

	public String parseContext(String context){

		return context.substring(0,context.indexOf(":"));

	}

}





class SSendThread implements Runnable{

	private Server server;

	public SSendThread(Server server){

		this.server = server;

	}

	public void run(){

		while(true){

			try {

				

				BufferedReader line = new BufferedReader(new InputStreamReader(System.in));

				String respMsg = line.readLine();

				if(respMsg.equals("quit")){

					server.quit(true);

					return;

				}

				sendRespMsg(respMsg);

				

			}catch(IOException e) {

				System.out.println("SSendThread  Wrong");

			}

		}

		

	}

	

	public void sendRespMsg(String respMsg){

		String newMsg = respMsg;

		if(respMsg.indexOf("a:") == -1 && respMsg.indexOf("b:") == -1){

			newMsg = "a:";

			newMsg += respMsg;

		}

		String name = newMsg.substring(0,respMsg.indexOf(":"));

		Socket s = server.getSocket(name);

		try {

			PrintWriter out;

			out = new PrintWriter(s.getOutputStream(),true);

			out.println(newMsg);

		}catch(IOException e){

			System.out.println("SSendThread  Wrong");

		}

	}

}

发送内容的格式：
a:xxxxx
b:xxxxx

其他不支持。

给你一完整的，作为一块砖。

修改后的客户端：

import java.net.*;

public class Client {

boolean isQuit;

socket = new Socket("10.144.200.165",6000);
}catch(Exception e){
System.out.println("wrong");
}
isQuit = false;
}
public void send(){
SendThread sd = new SendThread(this);
new Thread(sd).start();
}
public void server(){
ReceiveThread st = new ReceiveThread(this);
new Thread(st).start();
}

public void over(){
try{
out.close();
in.close();
socket.close();
}catch(Exception e) {
System.out.println("Wrong");
}

}
public Socket getSocket(){return socket;}
public boolean isQuit() {return isQuit;}
public void quit(boolean b){isQuit = b;}

public static void main(String[] args) throws Exception{
Client c1 = new Client();
c1.server();
Thread.sleep(1000);
c1.send();
}
}

class ReceiveThread implements Runnable{
Client cl;
public ReceiveThread(Client cl){this.cl = cl;}
public void run(){
BufferedReader in;
Socket socket = cl.getSocket();

while(true){

char[] buffer = new char[1024*1024*5];

/*while((lineStr = in.readLine()) != null){

int len = in.read(buffer,0,buffer.length);
System.out.print(new String(buffer,0,len));
}catch(IOException e) {

return;

再问下服务器端判断用户A B socket那段线程代码应该怎么写啊
[Quote=引用 1 楼 likefire 的回复:]
一般server段用多线程来实现。
这是我写的客户端，通过telnet连接服务器的，希望对你有帮助

Java code

import java.io.*;
import java.net.*;

public class Client {
Socket socket;
BufferedReader in;
PrintWriter out;
……
